I think this diagram should explain the differences: (URL) is the N-input differential output AND gate, developed from your sketch. I've used 2 switches for A, to gate the supply so that it doesn't leak. This gives 2+4++4 switches for an N-input (...) (19 years ago, 25-Aug-05, to lugnet.technic)

Does anyone know if the newer double bevel gears are stronger than the older lego technic gears? By stronger I mean won't break under pressure like the older ones. (19 years ago, 24-Aug-05, to lugnet.technic)
